QUnitX

What QUnitX is

QUnitX is a free, open-source test tool for JavaScript and TypeScript teams. It lets a team write a test file and run it with Node.js, Deno, or in a browser. The project describes setup without configuration files, a transform pipeline, injected globals, or runtime dependencies. Assertions include deep and partial equality, error matching, ordered steps, assertion-count checks, and per-test timeouts. Tests can be arranged in nested modules with before, beforeEach, afterEach, and after hooks. In the browser interface, users can filter tests, share a filtered view by URL, rerun a test, and inspect assertion differences. The linked qunitx-cli runs tests in headless Chromium, Firefox, or WebKit and streams TAP output to the terminal. It also supports esbuild plugins, GitHub-annotated output, JUnit XML, V8 coverage reports, and a JavaScript API. Core use requires Node.js 22 or later or Deno 2 or later; the CLI requires Node.js 24 or later or Deno 2.7 or later. QUnitX is ESM-only, and browser coverage has a source-map limitation.
